Nickel Alloy 825, Incoloy® 825
Incoloy® 825 is a nickel-iron-chromium alloy that also contains molybdenum, copper, and titanium in trace proportions. It is also known by the trade name Nickel Alloy 825. This combination gives Incoloy 825 greater corrosion resistance in the toughest situations. Like many of the alloys in the Incoloy family, Incoloy 825 gives consumers a variety of benefits:
Excellent resistance to oxidizing acids like phosphoric and sulfuric, as well as reducing acids like acetic and formic.
Helps avoid stress-corrosion cracking
Stops localized assaults such as pitting and crevice corrosion
Strong resistance to a wide range of oxidizing chemicals, including nitric acid, nitrates, and oxidizing salts
Incoloy 825 is utilized in a variety of businesses and applications thanks to the exceptional corrosion resistant properties that it possesses. These include the following:
Chemical processing
Pollution control
Calorifiers
Oil and gas recovery
Hot vessels for food, water, and seawater
Acid production
Pickling tank heaters, tanks, and equipment
Nuclear fuel reprocessing
Radioactive waste handling
Marine exhaust systems
Like most of the Incoloy family of alloys, Incoloy 825 has a unique chemical composition which includes:
Ni 38-46%
Fe 22% min
Cr 19-23.5%
Mo 2.5-3.5%
Cu 1.5-3%
Mn 1% max
Ti 0.6-1.2%
